The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
Answer is option B i.e. "Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion"
A pair of branched colleterial glands are present behind the ovary in female cockroaches. These glands open into the genital pouch separately, just above the spermathecal aperture and their secretion forms a hard egg case around the eggs called Ootheca.
While, the development of cockroach is hemimetabolous because there is no pupal stage in the transition from larva to adult.
